Abstract

PURPOSE:To alter the direction of the body with light load when a disabled person getting on and off with respect to a bed part by supporting a back part in a revolvable and liftable manner while supporting the position of a hip part above a base frame in a revolvable manner and also supporting foot parts above the base frame in a liftable manner. CONSTITUTION:When an old man 8 is taken down from a bed part 2, the foot part 2c of the bed part 2 is allowed to fall and, at the same time or about that time, a back part 2a is revolved to be raised. By this operation, the old man 8 rises while the his back is raised and becomes such a posture that his feets are supported at a position lower by one step. The foot part 2c is detached from the revolving region of a hip part 2b by falling and the back part 2a is revolved to be raised and the moving region of a head end part H is detached from a head board 12 and, therefore, the hip part 2b becomes a state revolvable along with the back part 2a without hindrance. Therefore, when the hip part 2b is revolved along the back part 2a, the old man 8 can be directed to the lateral part of bed and can be taken down from the bed part 2.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is suitable for use in beds, especially by people who cannot get on and off the floor as freely as healthy people, such as sick or elderly people. It concerns a bed.

(Prior Art and Problems) When a person who has limited physical freedom, such as a sick or elderly person, gets on and off the floor, it requires a great deal of effort not only for the person but also for the caregiver. For example, when lowering a person who is lying on the floor, the caregiver must first lift the person's back to get them up, then turn their body and place their feet on the floor. It must be directed towards the side. Such lifting of the back can be performed automatically on a conventional bed with a back floor that can be rotated, but changing the orientation of the body requires care, which places a heavy burden on the caregiver. Conventionally, no bed has been proposed that allows the user to easily change the orientation of the body.

The present invention aims to solve the above problems.

(Means for Solving the Problems) To explain the configuration of the present invention with reference to drawings corresponding to embodiments, the bed of the present invention first includes a floor part 2 supported above a base frame 1, a back part 2a and a bed part 2 supported above a base frame 1. It is divided into a waist part 2b and a leg part 2C, and the back part 2a and the waist part 2b rotate around the back part 2a! I] The waist part 2b is integrally supported so as to be able to descend, and the waist part 2b is supported so as to be pivotable above the base frame 1, and the leg part 2C is supported above the base frame 1 so as to be movable up and down. Configured.

Further, in the above-mentioned bed, the present invention has a swing support shaft 3 protrudingly installed below the waist portion 2b, and the swing support shaft 3 is rotatably mounted on a swing bearing 4 projecting above the base frame 1. A support member 5 for the back part 2a is provided on the pivot support shaft 3 to fix the back part 2a so as to be able to rotate up and down, and the @2 foot part 2C is attached to the pantograph mechanism 6 above the base frame 1.
It is supported so that it can be raised and lowered through.

Furthermore, in the above-mentioned bed of the present invention, the base frame 1 is provided with a support portion 7 for supporting the head side end H of the back portion 2a in a horizontal state.
has been established.

(Actions and Examples) The operation of the present invention will be explained with reference to examples.

An elderly person, etc. 8 lying supine on the floor part 2 on the bed of the present invention
When lowering the foot from the floor 2, first lower the foot 2G as shown in FIG. 1(a), and then simultaneously or concurrently with the lowering of the foot 2C, as shown in FIG. 1(b)c. Like back 2
Rotate and raise a. This action causes the elderly person 8 to lift his or her back and stand up, and assumes a posture in which the legs are supported at a lower position.

By descending, the foot 2C is removed from the rotation area of the waist 2b,
Further, as the back portion 2a rotates and rises, the movement area of the head side end H is removed from the headboard 12, so the waist portion 2b becomes able to rotate together with the back portion 2a without any inconvenience. Therefore, release the appropriate stopper (not shown) and move the waist 2b to the back 2.
By turning with the patient a, the elderly person 8 can be turned to the side of the bed in the above-described position, and thus can be lowered from the floor 2. When turning the waist part 2b, the caregiver only has to help the elderly person 8 move the legs, which are supported at a lower position by lowering the foot parts 2C mentioned above, and from there they are supported on the floor of the hospital room, etc. Since it is only necessary to lower the foot 2C to 9, the burden on both the caregiver and the elderly person 8 is much lighter compared to the case where the foot 2C is suddenly lowered from the height of the foot 2C when lying on the back.

Next, when placing the elderly person 8 on the floor 2, it is sufficient to perform the reverse operation as described above, and in this case as well, the lifting of the legs is necessary to change the direction of the elderly person 8 by rotating the waist 2b. teeth,
A foot part 2 supported at a low position from a floor part 9 of a hospital room, etc.
Since it is up to C, the burden is very light.

In the present invention, the back part 2a is integrally supported with respect to the waist part 2b so that it can rotate up and down, so it is supported in a cantilevered manner.
A support part 7 that supports the head side end H of the back part 2a in a horizontal state.
By providing this on the base frame 1, the load of the back portion 2a in such a horizontal state can be supported at both ends,
Furthermore, if the back portion 2a is in a tilted state, the load of the elderly person 8 will be shifted toward the waist portion 2a, so there is no problem with cantilever support.

Next, the rotation of the waist portion 2b position is achieved by, for example, providing a rotation support shaft 3 protruding from the lower side of the waist portion 2b, and supporting the rotation support shaft 3 so as to be able to rotate on a rotation bearing 4 protruding from above the base frame 1. This can be done by making the structure, and also the back 2
a is provided with a support member 5 for the back part 2a on the shaft 3, and is supported by this support member 5 so that it can rotate up and down, so that it is integrally supported with the waist part 2b and can rotate. . In the illustrated example, the mechanism for rotating and raising and lowering the back part 2a is constructed by connecting a connecting arm 10 protruding from the support member 5 and an elastic rod 11 such as a gas spring between a suitable position on the head side of the back part 2a. ing. In addition to the above-mentioned configuration, a pivoting mechanism at the waist 2b position, an operating mechanism for enabling or disabling pivoting, and a support mechanism for the back 2a are appropriate.

Further, the foot portion 2C can be raised and lowered by, for example, supporting the foot portion 2C above the base frame 1 via the pantograph mechanism 6, but the 11th rule for raising and lowering the currency can also be applied. can do. In addition to the parallel elevation using the pantograph mechanism 6 or the like, the ascending and descending mode may be arbitrary, such as a mode in which only the waist portion 2b side is elevated. Further, in such a stomach descent mechanism, a mechanism that supports the foot portion 2C at an upper position and a lower position is also suitable.

(Effects of the Invention) As described above, the bed of the present invention is constructed by dividing the floor part supported above the base frame into a back part, a waist part, and a foot part, and the back part and the waist part can be moved up and down by rotating the back part. In addition, the waist position is supported so as to be pivotable above the base frame, and the feet are supported above the base frame so that they can be raised and lowered, so that it is possible to This has the effect that a person who cannot use his or her body as freely as desired can change the orientation of the body, which is necessary when getting on and off the floor, with a very light burden.
